The OEE score is expressed as a percentage. What would a score of 100% represent?

A score of 100% in Overall Equipment Effectiveness (OEE) signifies that a manufacturing process is operating at its maximum potential in terms of availability, performance, and quality. This means that all machinery is always available when needed, that production is perfect with no defects, and that capacity is fully utilized without any delays.

Achieving 100% OEE is an ideal state representing flawless operations, where there are no downtime incidents, no speed losses, and no defects produced. Each component of OEE—availability, performance, and quality—contributes equally to this perfect score. Thus, a score of 100% could only be attained when all operational aspects are optimized simultaneously, providing a comprehensive overview of the manufacturing process's efficiency.
